IMPROVEMENT IN CLOCKS.

Specification forming part of Letters Patent N0. 180, 138, dated July 25, 1876; application filed July 3, 1876.

To all whom it may concern:

Be it known that I, FLORENCE KROEBER,

of Hoboken, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Clocks, of which the following is a specification Figure l is a face view, partly in section, of inyimproved clock. Fig. 2 is a detail face view of the improved transparent drop-gate devised by me 5 Fig. 3, a vertical transverse section of the same.

Similar letters of reference indicate corresponding parts in all the figures.

This invention relates .to a new drop-gate placed in clock-cases in front of the pendulum, to give access thereto. My invention consists in making the same of glass, of which the upper part is set in a frame, that supports the gate upon the base of the clock-case.

The letter A represents the case of the pendulum-clock. In front of this case an aperture, a, is left, to allow access to the pendulum B, and to allow its height to be regulated, and its motion to be arrested or started. This aperture to is closed by my improved removahle drop-gate O, which is constructed of a plate, b, of glass, and of aprojecting border or rim, d, that embraces the upper part of said glass. The ends or shoulders e e of said border d serve to support the drop-gate in a vertical position on the projecting base or moldingfof the clockcase, and in this position the lower part of the glass 1) extends behind the base, as in Fig. 3, and aids in holding the gate in position, leaving it, however, freely removable. The upper part of the glass closes the aperture a, and yet allows the pendulum to beseen, so that one can always know whether the clockwork is in motion or not.

FLORENCE KROEBER.
